Inter- and intraobserver error tests were conducted after the pilot studies in order to gauge the usability of each trait definition.
When Saunders (1978:i) wrote her dissertation she looked at over 50 postcranial nonmetric traits and stated that many of the nonmetric traits she researched were "too subjective to be described properly and should be eliminated." For this study, the creation of definitions, illustrations, and an ordinal scoring approach were tested utilizing statistical techniques to examine interobserver and intraobserver error. While all visual assessments are susceptible to cognitive biases (Nakhaeizadeh et al.
Intraobserver error was tested by the author observing and scoring 15 skeletons on two separate instances one month apart.
The intraobserver error is calculated by repeated measures, and the statistical significance was set at P < 0.05.
That could be explained to be that the intraobserver error is very small and even insignificant statistically.
A pilot study undertaken on 35 faces "landmarked" six times each at 62 landmark sites by two observers was used to evaluate inter- and intraobserver error and the effectiveness in discriminating between faces associated with each landmark.
Without independent confirmation by multiple observers and without video documentation, the chance of inter- and intraobserver error increases.
The traits were evaluated and ranked using a collection of skulls of known sex, by setting the indicators in the determination of sex with a high degree of accuracy (>80%), and with a low intraobserver error (<10%).
We calculated the level of accuracy in the determination of sex, according to the parameters outlined and established sensitivity for the diagnosis of male and female, as well as the intraobserver error.
By the remediation method a random sample of 40 skeletons intraobserver error were found.
In the precision test, the sample (n = 40) was measured again revealed some discrepancies between the first and second measurement, producing an intraobserver error 5.04%, the highest error values were found in the size and overall architecture of the skull and in the size and roughness of the mastoid process, however all values were considered acceptable because they were below 10% intraobserver error.
